sAsH STRUCTURE Filed Jan. 14, 1957 United States Patent O sAsH STRUCTURE 'Go'rge H. lleiik'e, Chicago, VIll., ssgor of one-half to Julius J. hlis, Chicago, lll. Application January 14, 1957,seria1N0. 634,011 2 Claims. (ol. zii-'53) This 'invention is a sash structure, 'the primary object of which is lto provide an all 'metal sash for the support of diaphanous panels or panes in window openings in buildings, ithe structure of which is such as `to 'enable the sash to be readily assembled in the building in an economical and facile manner and without the exercise of unusual skill and knowledge.

A further object of the invention is to provide a sash structure whose principal elements are formed of extruded aluminum or similar rne'tal and wherein the several p-arts constitl'lting the completed vsash are assembled securely in proper relationship with one another `so as to provide a Irigid structure capable of adequately supporting the pane or panel and which may be readily removed for repair or other purposes when desired in an expeditious manner.

A further object of the invention is to provide a sash structure with its parts so constructed and arranged that the panel as4 well as the window opening is tightly sealed at all times against the admission of moisture or air.

A still further object is to provide a sash structure which may be made and secured together in sections whereby to adequately support illuminating panels in an opening of abnormal size, and wherein improved means are provided for securing the edges of complemental panels in tight relationship and sealed against the passage of air or moisture therebetween.

With the foregoing objects in View, together with others which will appear as the descrip-tion proceeds, the invention resides in the novel construction, combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawing, and particularly pointed out in the claims.

In the drawing:

Fig. l is a vertical sectional view taken through the construction plates of a window opening of a building and illustrating as applied thereto a sash structure involving the invention, and

Fig. 2 is a transverse fragmentary sectional view taken substantially upon line 2 2 of Fig. 1.

Referring now more particularly to the drawing, parallel plates, such as angle plates 3 and 4, are arranged in spaced relationship horizontally and define the -top and bottom of the opening in which the window frame is to be located.

The sash frame of my invention involves head and sill rails S and 6 respectively, formed in the present instance preferably of extruded aluminum, spaced apart in parallel relationship a distance sutiicient to be accommodated between the upper and lower parallel plates 3 and 4. 'Ihe head rail is provided with spaced depending anges 8 coextensive with the rail, while the sill rail is provided with similarly spaced upstanding iianges 9 to provide pockets, each of the said pockets opening toward one another and in alignment with each other. These rails are connected by upstanding sash bars of metal indicated at 10, the upper and lower ends of the bars being attached to rearwardly projecting portions 11 and 12 of the ICC 2 head and sash rails respectively, by Vangle plates' 13. It will be noted particularly "with reference 'to Fig. lof the drawing that the 'forward edge of the sash bar 10 will be disposed in substantial alignment 'with the pockets in the head and sill r'ail's respectively. lBolts or rivets may be utilized in securing the angle plates 13 to the extensions "1l-12 of "the in Vi'cier 'to Ve'ect a rigid construction. As inany Vof vthe sash bars may be "required will ybe used in "the constructiony l The illuminating 'panel or pane is indicated at 415 and is of a 'size to eiite'rd between the head andfsill rails with ends seated inthe -po kts'of said rails, insulating material or rgaskets 1`6 effecting a tight "seal between -the edges of the panel arid 'the 'walls of the pckets. It be observed thatrth'e rear face of Vthe panel abuts the forward edge 'of 'thesash bar 10.y The pane or panel 15 is securely 'anchoredt lin place and lheld in l'the frame by -i'neans 'of kglazing caps v17; the said caps being formed of any suitable material and f a length to lit between 'the head and sill "rails as shown in Fig. l. These glazing caps are of substantially -'s'hape in cross section as shown in Pig. 2, vand are arranged so as 'tol straddle the ends of the panels las shown. In order to s'ecure the "glazing -caps properly position, screws are passed 'thrugh "the crowns of the caps and threadedly engage in socket membersv 1S in the adjacent facepof the 'sash '10. The :bars may be provided with laterally dellected 'wings 1'9 nto overlap vthe 'inner edges of the panes or panels, and it will be understood that suitable insulation may be employed between these wings and the adjacent edges of the panels to secure a tight sealing arrangement when the screws 201 are passed through the glazing caps and into the sockets 18.

The rearwardly dellected or extruded portion 11 of the head rail 5 is provided with a forwardly projecting lip 21 throughout its length to engage over an inturned wing 22 projecting from a hinge plate 23 secured as at 24 to the `overhead anchoring plate 3. A guard 25 also secured to the plate 3 is positioned beyond the end of the wing 22 in order to maintain the hinge connection between the lip 21 and the wing 22. Inasmuch as the hinge plate 23 is coextensive with the sash frame, it is app-arent that the hingeconstruction described is housed against the passage of air or moisture therethrough.

The rearwardly projecting portion 12 of the sill rail 6 is provided with an upstanding plate portion 30 to overlie the lower angle plate 4, a sash anchor 31 coextensive with the frame being secured to the upper end of the plate portion 30 by screws or rivets 32 to elect a rigid connection between these parts. This sash anchor 31 drops behind the upstanding flange of the base plate 4 so that a rigid mounting of the lower end of the frame is attained and a connection between the lower sill and the adjoining plate is rendered weatherproof.

In assembling the sash, it is but necessary to engage the forwardly projecting lip 21 with the inwardly directed wing 22 of the hinge plate 23, after which the sash anchor 31 is applied in the manner `described and shown in Fig. l and secured in position by the bolts or rivets 32.

In instances where the Window opening is of abnormal width, a number of panes or panels 15 are employed in order to provide effective and desired lighting. In such instance, a desired number of upstanding sash bars are employed and installed in the manner described, one each at the abutting edges of adjoining panels. The glazing caps are applied in the manner set forth to securely anchor the adjoining ends of panels and to securely seal them against the passage of air or moisture. In such instance, it may be desirable to provide an additional anchor for the entire assembly of panels, in which event a connector plate 35 may be secured at its ends within the building structure and across the opening in such position as to engage the inner edges of the sash bars nected at its inner end to said upper plate and having its opposite edge disposed laterally beyond the plane thereof, a head rail hingedly connected throughout its length at one of its sides to said outer edge of said hinge plate, spaced parallel flanges depending from said outer rail edge coterminous with the latter to a pocket between them, a sill rail secured at its inner edge to and projecting laterally from the lower of said plates, spaced flanges coterminous with said sill rail projecting upwardly from the outer edges thereof to provide between them a pocket in alignment with the pocket of said head rail, a panel seated at its upper and lower ends respectively in the head and sill pockets, gaskets in each of said pockets enclosing said panel ends, a sash bar rigidly connected at its ends to said head and sill rails inwardly of said pockets and having one edge in substantial engagement with said panel, and means for securing said panel to said sash bar.

2. In a sash structure, upper and lower parallel plates secured in spaced relationship, a hinge plate rigidly connected at its inner end to said upper plate and having its opposite edge disposed laterally beyond the plane thereof, a head rail hingedly connected throughout its length at one of its sides to said outer edge of said hinge plate, spaced parallel anges depending from said outer rail edge coterminous with the latter to provide a pocket between them, a sill rail secured at its inner edge to and project- Iing laterally from the lower of said plates, spaced llanges coterminous With said sill rail projecting upwardly from the outer edge thereof to provide between them a pocket in alignment with the pocket of said head rail, panels seated at their upper and lower ends respectively in the head and sill pockets with their edges in spaced relationship, gaskets in each of said pockets enclosing References Cited in the tile of this patent UNITED STATES PATENTS 1,433,441 White Oct. 24, 1922 1,803,514 Thomas May 5, 1931 1,906,997 Neeb May 2, 1933 1,925,817 Plym Sept. 5, 1933
